Abstract (en)
[origin: US2014356087A1] A vacuum drilling system and methods is provided that may utilize both a through tool coolant supply as well as a central vacuum extraction system. The system may include a cutting head provided on a hollow tube and a vacuum source to apply vacuum pressure to the area of the cutting head via one or more chip inlets arranged proximate to the cutting head. Sealed coolant containment channels supply coolant to the area of the cutting head.
